Abstract
We developed a victim data base (“1999-2018”) for heavy rainfall disaster events in Japan
from 1999 to 2018, and 1259 victims were classified. The purpose of this study is to analyze
the characteristics of victims caused by heavy rainfall disaster by typhoon No.1919 (“T1919”)
in comparison with “1999-2018”. Through this heavy rainfall event, 88 people were killed or
missing in western Japan. Characteristics of victims by ““T1919” were as follows: 1) 72% of the
victims were death by flood disaster. This is the highest ratio for heavy rainfall disaster events
since 1999. 2) 58% of victims died outdoors. 54% of them died while driving their car. This is
the highest ratio since 1999. The danger of outdoor activities in heavy rain was shown again. 3)
66% of the victims due to flood disaster died near the flood disaster hazard area. The ratios is
higher than “1999-2018”. 93% of flood victims died in potentially flooded lowlands. This ratio
is consistent with “1999-2018”. Understanding for hazard map information is important for the
disaster prevention.
